IMPROVED WASHING MACHINE.

TO ALL WHOM IT MAY CONOERN:

De it known that I, G.C. SELFRIDGE, of Saratoga Springs, in the county of Saratoga, and State of New York, have invented a new and improved Washing Machine; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the sam reference being had to the accompanying drawings forming part of this specification.

Figure 1 represents a longitudinal sectional elevation of my improved washing machine.

Figure 2 is a transverse sectional elevation of the same.

Similar letters of reference indicate corresponding parts.

This invention relates Yto certain improvements on the washing machine for which Letters Patent were granted to John M. Oakley, September 17, 1861, and consists in converting the maehine,lthe parts of which are of similar construction as those of lthe machine described in the aforesaid Letters Patent, into a double-acting washing machine by corrugating the whole ,bottom and both ends of the suds-box on the inside, and by roughen- ,ing the faces of the plunger-s at both ends; thereby the plungers will operate at both ends of the washing machine, and twice as much work canibe done as by the single washing machine.

The invention also consists in so fastening the connecting-rods to the pendulous arms carrying the plungers that they can be easily disengaged from the said arms, toallow the opening of the hinged cover at that end of lthe snds-box, above which the yconnecting-rods are arranged.

The invention consists also in making the corrugated bottom and ends of the suds-box removable from the same, and in forming it of two separate pieces, so that each piece can be taken out through the hinged cover 'at that end of the snds-box, near which it is arranged. This allows the box as well as the board to be easily cleaned.

A. represents a suds-box, made of wood: or other suitable material, of rectangular form, as shown. It is supported by suitable posts or standards B B, and is covered by a board, C, in which two hinged covers, D D', are formed, onenear each end of the box. E is a semi-.elliptic corrugated wash-board, arranged within the sudsbox, so as to cover the ends and bottom of the same, asshown in tig. 1. It is made of two halves, a and a, each of which its .loose in the box. The two pieces are in contact with each other at or near the centre of'the box. When the covers D and D are opened, the boards a and a can be taken out, each one through the opening under which it is arranged. The box, as well as the wash-board, can thus be easily cleaned. F F are two standards, projectingfrom the sides of the suds-box at or near the centre of the same.. vIn their upper ends are the bearings for an oscillating shaft G, to which two or more ,pendulous arms I-I H are rmly secured. The arms II it through slots in the cover C of the bo'x, and to their lower ends are secured plungers I I, as shown in fig, 1. Each plunger has both ends roughened or step-shaped, as shown, so, that when the pendulous arms are set in motion, each plunger will once move towards one end and then towards the other end ofthe machine, operating in connection with the wash-board E, upon the clothes placed in each end of the suds-box. .I is a horizontal crank-shaft, having its bearings in studs projecting from the sides ofthe box A, near vone end ofthe same. To the cranks formed on this shaft are secured connecting-rods K K, which are hook-shaped or notched at or near their outer ends, so that they can be easily fitted upon or taken off pins b b, which project from the arms H, as shown.

By turning the shaft J by means of a belt, crank, treadle, or otherwise, the arms II will be set in motion, and the plungers will be moved back and forth in the sud's-box. As the rods K K are arranged above the cover D, so that the latter cannot be opened as long as the shaft and pendulous arms are connected, it is neces-v sary that the rods 'K can be released from the pendulous bars II, as indicated by red lines in fig. 1. For this purpose the ends of the rods K are hook-shaped or notched.

I claim as new, and desire to secure by Letters Patent- The combination' of the slotted cover C, hinged lids D D', sectional wash-board E, double oscillating. plungers I, arms H, rock-shaft G, removable connecting-rods K, working' above the lid of the ends-box, pins b, crank-shaft J, as herein described for the purpose specified.
